Resource Estimates Technical Reports (NI 43-101)

Battery Mineral Resources Corp. Announces the Filing of its NI 43-101

Technical Report for the Resource Estimate at its Punitaqui Copper Mine

Vancouver, British Columbia – (October 3, 2022) – Battery Mineral Resources Corp.

(TSXV: BMR) ("BMR” “Battery" or the "Company") is very pleased to announce that

it has filed a technical report for its NI 43 -101 resource estimate at Punitaqui on

SEDAR. This report is authored by JDS Mining and Energy Inc. (“JDS”).

The technical report includes sections pertaining to the project history, geology,

exploration, drilling, adjacent properties , sampling, QA/QC, data validation,

metallurgy, mineral resources, conclusions, and recommendations as well as other

required sections. The main highlight is the indicated and inferred resources which

can be seen in the Table 1, below.

Notes to the Sulphide Mineral Resource Estimate Table

• Prepared by Garth Kirkham (Kirkham Geosystems Ltd.) an Independent Qualified Person in accordance with NI 43 -101.

Indicated

Zone Cut-off (% CuT) tonnes CuT (%) Ag (g/t)

San Andres 0.70 1,736,000 1.06 4.83

Cinabrio 0.70 378,000 1.55 0.00

Cinabrio Pillars 0.70 1,027,000 1.51 0.00

Cinabrio Norte 0.70 833,000 1.01 4.57

Dalmacia 0.70 2,198,000 1.00 1.38

Indicated sulphides 6,172,000 1.14 2.47

Inferred

Zone Cut-off (% CuT) tonnes CuT (%) Ag (g/t)

San Andres 0.70 303,000 0.82 4.03

Cinabrio 0.70 90,000 0.98 0.00

Cinabrio Pillars 0.70 0 0.00

Cinabrio Norte 0.70 1,078,000 0.98 4.91

Dalmacia 0.70 1,599,000 0.93 1.00

Inferred sulphides 3,070,000 0.93 2.64

• Effective date: August 16, 2022. All mineral resources have been estimated in acco rdance with Canadian Institute of Mining and

Metallurgy and Petroleum (“CIM”) definitions, as required under NI 43 -101.

• Mineral Resources reported demonstrate reasonable prospect of eventual economic extraction, as required under NI 43-101. Mineral

Resources are not Mineral Reserves and do not have demonstrated economic viability. The Mineral Resources may be materially

affected by environmental, permitting, legal, marketing, and other relevant issues.

• Cut-off grades are based on a price of US$3.50/lb copper, US$20/oz silver and several operating costs, metallurgical recoveries,

and recovery assumptions, including a reasonable contingency factor.

• Historic work at the Cinabrio Mine did not include silver analyses therefore silver grades are assumed t o be at a null grade for the

purpose of completeness however, it is reasonable to assume that silver grades will be at a similar tenor as Cinabrio Norte.

• An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Min eral Resource and must not be

converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded t o

Indicated Mineral Resources with continued exploration.

• Resources reported for Cinabrio, San And reas, Cinabrio Norte and Dalmacia are reported with internal dilution applied but are not

fully diluted.

Note that all four zones of the resource estimate (the Cinabrio mine, the Cinabrio

Norte zone, the San Andres zone and the Dalmacia zone) have undergr ound access

previously established by prior operators of the Punitaqui mine complex.

Battery’s CEO and director, Martin Kostuik states, “we are extremely pleased to have

completed the very comprehensive Punitaqui Technical Report . This report

encompasses four different deposits, including Cinabrio which is the deposit that was

the main source of ore for the Punitaqui copper concentrator for the nine plus years

of operating history. We are very encouraged with the results of our drilling program

but also encouraged by the opportunity we have to continue adding resources in not

only all four deposits but throughout our significant land package of 8,693 hectares.

In addition, the report displays the large amount of work including engineering,

permitting and metallurgy which has been focussed on both de -risking and

uncovering opportunities at this very promising project. Work is nearing completion

to apply best practices to these new resources with the intention of arriving at sound

conclusions regarding project economics and mine life. It is the full intention to use

these conclusions to obtain the remainder of funding required for the recommencing

of mine operations this year, followed closely by copper concentrate production at

the Punitaqui mill. On behalf of the Board of Directors of the Company I’d like to

thank the people at JDS as well as our team in Chile for their hard work in

accomplishing this major milestone for the company.”
